An enjoyable day outing from Whitney portal. Climb the obvious couloir splitting the south east face of Thor Peak. Once at the top of the couloir, head out onto the large summit plateau, head right towards the true summit.

Mostly class 2 with a couple of short class 3 steps. Very enjoyable as a winter route. Either descend the way you came, or head down scree/talus slopes to the west depositing you at Lower Boy Scout Lake

South east couloir

The Stemwinder

An "old school" (1936!) route which winds its way up the right-side of the huge south face of Thor Peak.

Traverse left on a ledge from the near the right-end of the south face to get to the start of the route. A 10' class 3-4 chimney must be overcome to get to P1. P1 is marked with a fixed piton and stopper right off the deck. Make the crux 5.4 chimney move and gain easier ground heading up and right. Many options exist between class 3 and easy 5th. Choose your own adventure. You are aiming for a small red pinnacle which is passed behind from the left. Some easy but very exposed slab moves out right lead to left-leaning ramps/cracks, marked with the occasional fixed angle-piton. Once on the ridge, head west up class 2 talus to the summit of Thor Peak. I descended the north-east slope into the N Fork of Lone Pine Creek. If you do this, you will need to carry all your stuff. There may be another descent nearer to the south face.
